Markdown Viewer

Double-click a Markdown file and it's just there.

The Preview.app macOS never had for Markdown. Double-click a .md and it renders instantly — headings, code, tables, images, the lot. One key to edit the source and save. All on your Mac.

What it does

Open. Read. Edit. Done.

👀

Renders instantly

Double-click any .md — CommonMark + GitHub flavour, in a clean reading theme that follows light/dark.

🔍

Quick Look preview

Tap space on any .md in Finder and it renders right there — the same theme, no need to open the app.

✍️

Edit & save

Press ⌘E to edit the source, ⌘S to save. It never silently overwrites a file that changed underneath you.

🖼️

Images just work

Pictures next to your note render in place — resolved safely from the note's own folder.

📄

Your default .md app

Offers to open every Markdown file on your Mac, so they stop opening as raw text.

The promise

Local and yours.

No cloud, no account, no library to import into. It's the anti-Obsidian: your files stay plain .md in your folders, and this just shows them beautifully. Free — a paid Viewer Pro with extra tools comes later.
